Intra-ocular camera head for visual prosthesis

Abstract

An intraocular camera used for visual prosthesis belongs to the technical field of medical equipment. In the present invention, the gradient refractive index lens and the CMOS image sensor are seamlessly connected, the annular solar cell completely wraps the gradient refractive index lens and the CMOS image sensor inside, and the annular solar cell is connected to the CMOS image sensor to provide stable stability for the CMOS image sensor. Operating Voltage. As an optical lens, the gradient index lens has a short focal length and can achieve seamless connection with the CMOS image sensor, reducing the axial size of the system. The designed low-pixel CMOS image sensor not only reduces size and power consumption while meeting the requirements for object recognition. It is powered by a ring-shaped solar cell, which is safe and has no toxic side effects on the human body. Once implanted, there is no need to replace the battery. The ring-shaped design conforms to the shape of the human pupil and is small in size for easy implantation.

Description

technical field [0001] The invention relates to a device in the technical field of medical equipment, in particular to an intraocular camera for visual prosthesis. Background technique [0002] In recent years, many camera systems using solid-state imaging elements have been developed, which can collect image information in real time and are widely used in medical treatment, monitoring, security, etc. However, in order to meet the needs of various applications, they usually have high pixels and high resolution, complex functions, large size, and high power consumption, which cannot meet the requirements of visual prostheses. [0003] Existing camera systems usually use common lenses as optical lenses, which have a long focal length and large size, are difficult to process, are inconvenient to implant, and have high production costs. [0004] At present, button batteries are usually used as power sources in miniature imaging devices, which are small in size and easy to impla...

AI Technical Summary

Problems solved by technology

But its disadvantages are: the button battery contains substances harmful to the human body, it is obviously inappropriate to stay in the human body for a long time, and when the battery is exhausted, it is more troublesome to replace the battery

"Its shortcoming is: 1. Adopt CCD camera as imaging device, 2. Self-focusing lens (namely gradient refractive index lens) does not consider shortening focal length, realizes seamless joint with CCD, so this system is only to a certain extent Miniaturization has been achieved, but for the needs of the camera in the eye of the visual prosthesis, the system is obviously too large to be implanted

And the system does not take into account the power supply design part
